MAX203ECWP+G36

Drivers, Receivers, Transceivers Overview

The MAX203ECWP+G36 is a single-supply RS-232 transceiver from the MAX202E–MAX213E family, manufactured by Analog Devices Inc./Maxim Integrated. It features two drivers and two receivers operating at data rates up to 120kbps. The device integrates internal charge-pump capacitors, eliminating the need for external components. It operates on a single +5V supply (±5% tolerance) and provides ±15kV ESD protection on all pins. The EC suffix indicates an industrial temperature range of 0°C to +70°C. It is housed in a 20-pin Wide SOIC package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated charge pump circuitry eliminates the requirement for external capacitors or bipolar power supplies.
• High electrostatic discharge protection rated at ±15kV Human Body Model on all pins.
• Single +5V supply operation with low shutdown current consumption.
• TTL/CMOS compatible logic levels with tight receiver input thresholds.

Drivers, Receivers, Transceivers Applications

• Battery-powered equipment requiring minimal component count
• Hand-held diagnostic tools
• Portable communication devices

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix G36 against the manufacturer's current datasheet to confirm lead-free status and RoHS compliance. Confirm that the Wide SOIC package dimensions match the target PCB footprint. Check for any recent lifecycle notices regarding obsolescence or last-time buy dates.

Drivers, Receivers, Transceivers Selection Notes

Select this part when board space savings are critical due to the elimination of external charge-pump capacitors. Ensure the application requires only two driver/receiver channels. Verify that the 0°C to +70°C temperature range meets the environmental requirements, as higher temperature variants exist within the same family.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX202E–MAX213E family of RS-232 transceivers. Unlike other members such as the MAX202E which require four external capacitors, the MAX203E variant integrates these capacitors internally. This distinguishes it from the MAX205E, which offers five channels but also uses internal capacitors.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the same family include the MAX203EEWP+G36 for extended temperature ranges (-40°C to +85°C). Other family members like the MAX202E require external capacitors and are not direct drop-in replacements without schematic changes.
